Today marked two key events for the 2017-18 Champions League. The group stages were announced and adidas has unveiled the Champions League match ball for this upcoming season. According to the three stripes:
"The new ball features the established star-panel design inspired by the UEFA Champions League Logo that has become a feature of adidas UCL Official Match Balls. The 2017/18 version comes infused with new energy thanks to a dramatic blue and turquoise thunderstorm graphic.
The design ensures optimal performance for players in any condition. An outer texture coating, consistent across all adidas UCL Official Match Balls, offers secure grip and complete control while the thermally bonded star panels provide a seamless surface for an improved first touch. Taking a picture with flash will reveal a thunderstorm graphic on all of the uppers."
Side note - I need to try the "taking a picture with flash will reveal a thunderstorm graphic on all the uppers" thing. That sounds rad.
